Difference between request() & request_once(), include() & include_once() ?

Guys, what's the difference between request() & request_once(), include() & include_once() ?  I did some Google search but didn't find anything reliable.  Thanks.

require "file.ext";

 

This will require the file and give an error killing the page like a die() command if it fails or the file has already been required

 

require_once "file.ext";

 

Same as require but command is ignored if the file has already been required.

 

include "file.ext";

 

This will give an error if it fails but continue running the script like the trigger_error() function

 

include_once "file.ext";

 

will be ignored if the file has already been required, give an error if it fails and continue the rest of the script.

 

I think thats how it goes anyway

Just clarifying - You did mean 'require', not 'request'... ?

 

Is there any significant difference or reason why I should use

 

require ("file.ext");

 

versus

 

require "file.ext";

Oh yeah, I meant require() and not request(), sorry!

 

Thanks guys.  I appreciate it.

nope, require is a "keyword"...just like print...so you can use it with or without the parenthesis
